In recent years, DNA sequences (nucleotide sequence) of mt-DNA and Y chromosomes were considered for the study of human evolution, because:
 

1. They are small, and therefore, easy to study
2. They are uniparental in origin and do not take part in recombination
3. Their structure is known in greater detail
4. They can be studied from the samples of fossil remains
